Description

Technical Field

[0001] The present invention relates to the technical field of nitrogen production equipment, and particularly to an energy-saving equalizing hole device for a nitrogen generator. Background Art

[0002] As is well known, a nitrogen generator refers to a device that uses air as a raw material and separates oxygen and nitrogen therein by physical methods to obtain nitrogen. Industrial nitrogen generators can be classified into three types according to different classification methods, namely, cryogenic air separation method, molecular sieve air separation method, and membrane air separation method; a nitrogen generator is a nitrogen production device designed and manufactured according to the pressure swing adsorption technology; the nitrogen generator uses high-quality imported carbon molecular sieve as an adsorbent and separates air by the pressure swing adsorption principle at room temperature to produce high-purity nitrogen; usually, two adsorption towers are connected in parallel and are automatically operated by an imported pneumatic valve controlled by an imported PLC, alternately performing pressurized adsorption and decompression regeneration to complete nitrogen-oxygen separation and obtain the required high-purity nitrogen; the nitrogen generator specialized for the oil and gas industry is applicable to fields such as nitrogen protection, transportation, covering, replacement, emergency rescue, maintenance, and nitrogen injection for oil production in onshore oil and gas exploration, offshore and deep-sea oil and gas exploration, and has characteristics such as high safety, strong adaptability, and continuous production.

[0003] For the nitrogen generator with a split gas distributor proposed in the above patent document, during actual use, the surface of the distributor structure inside the separator lacks an automatic cleaning and dredging mechanism. Since the equalizing holes of the distributor generally have a small aperture, it is easy to cause blockage inside the equalizing holes after a certain period of use, affecting the normal use of the separator, and manual maintenance and cleaning are required, which is not conducive to improving the processing efficiency.

[0004] When the nitrogen generator with a split gas distributor proposed in the above patent document is actually used, the surface of the distributor structure inside the separator lacks an automatic cleaning and dredging mechanism. Since the equalizing holes of the distributor generally have a small aperture, it is easy to cause blockage inside the equalizing holes after a certain period of use, affecting the normal use of the separator, and manual maintenance and cleaning are required, which is not conducive to improving the processing efficiency. Summary of the Invention

[0005] The present invention discloses an energy-saving pressure equalizing hole device for a nitrogen generator. To achieve the above object, the present invention adopts the following technical solutions: A gas-liquid separator is a device for separating liquids and gases. When using a gas-liquid separator, we often encounter situations where a large amount of gas enters the separator, causing an instantaneous change in its internal pressure and even damaging the equipment. Therefore, in order to ensure the normal operation of the gas-liquid separator, it is necessary to open pressure equalizing holes on it to achieve pressure balance and stable flow field.

[0006] A pressure equalizing hole refers to a hole provided on the gas-liquid separator for achieving pressure balance. Its function is to transfer and disperse the gas pressure, reduce the fluctuations of the liquid level and gas level inside the separator, and ensure that the separator can work stably. At the same time, the pressure equalizing hole can also improve the flow field structure inside the gas-liquid separator and increase the smoothness and stability of the flow.

[0007] An energy-saving pressure equalizing hole device for a nitrogen generator includes an equipment cylinder. The lower surface of the equipment cylinder is fixedly connected to a reduction gearbox. The side surface of the reduction gearbox is fixedly installed with an air inlet pipe. The inner wall of the reduction gearbox is fixedly provided with a number of flow disturbing partitions. The reduction gearbox is used to reduce the pressure and speed of the gas; It should be noted that by providing a reduction gearbox at the air inlet end of the equipment cylinder, a number of flow disturbing partitions inside the reduction gearbox can form a curved gas channel inside the reduction gearbox, so as to use the curved channel to disturb and decelerate the gas, slow down the speed of the gas entering the equipment cylinder, and thus reduce the gas pressure to facilitate further pressure reduction and speed reduction of the air subsequently; An equalizing plate is arranged inside the equipment cylinder. A number of flow equalizing holes are opened on the surface of the equalizing plate. An anti-blocking mechanism is arranged inside the equipment cylinder. The anti-blocking mechanism is used to dredge and clean the flow equalizing holes; It should be noted that by arranging an equalizing plate inside the equipment cylinder, a number of flow equalizing holes on the surface of the equalizing plate can be used to evenly distribute and divide the high-pressure gas entering the equipment cylinder, achieve the transfer and dispersion of the gas pressure, reduce the fluctuation of the gas level inside the equipment cylinder, and keep the equipment cylinder working stably. The equalizing plate can also improve the flow field structure inside the equipment cylinder and increase the smoothness and stability of the gas flow; The anti-blocking mechanism includes a limit support pipe. A rotary movable frame is fixedly connected to the surface of the limit support pipe. A strip-shaped cleaning brush is fixedly connected to the upper surface of the rotary movable frame. An extension conduit is fixedly connected to the upper surface of the rotary movable frame. The top end of the extension conduit is fixedly connected to a shunt pipe. A number of jet nozzles are fixedly installed on the lower surface of the shunt pipe. The inner bottom wall of the equipment cylinder is fixedly connected to a transmission box, and a drive box is arranged on the back of the equipment cylinder.

[0008] In a preferred embodiment, the bottom end of the extension conduit extends into the interior of the drive box and is fixedly connected to a driven gear. A drive tube is rotatably arranged on the inner wall of the drive box. The front end of the drive tube is fixedly connected to a drive gear, and the drive gear meshes with the driven gear. A rubber tube is rotatably arranged between the end of the drive tube and the bottom end of the extension conduit.

[0009] In a preferred embodiment, a drive motor is fixedly installed on the inner wall of the drive box. The output shaft of the drive motor is fixedly connected to a first gear. The end of the drive tube away from the drive gear extends into the interior of the drive box and is fixedly connected to a second gear, and the first gear 15 meshes with the second gear.

[0010] In a preferred embodiment, an air pump is fixedly installed on the inner wall of the drive box. The output end of the air pump is fixedly connected to an air guide tube. The end of the air guide tube away from the air pump is rotatably connected to the input end of the drive tube. The output end of the air pump is fixedly connected to a ventilation tube, and the end of the ventilation tube away from the air pump extends to the outside of the drive box.

[0011] It should be noted that by arranging an anti-blocking mechanism inside the equipment cylinder, the drive motor can be used to drive the drive tube to rotate, and then the strip-shaped cleaning brush on the surface of the rotating movable frame can be used to clean the bottom of the pressure equalizing plate by the drive tube. At the same time, the air pump is used to convey air into the shunt tube at the top of the extension conduit, and a plurality of jet heads at the bottom of the shunt tube are used to jet air on the top of the pressure equalizing plate, so as to achieve the purpose of dredging the flow equalizing holes and improve the cleaning effect on the pressure equalizing plate. In a preferred embodiment, a fixed frame is fixedly connected to the inner wall of the equipment cylinder, and the limit support tube is rotatably connected to the surface of the fixed frame through a bearing.

[0012] In a preferred embodiment, four movable push rods are fixedly connected to the upper surface of the pressure equalizing plate. The four movable push rods are evenly distributed in a rectangular array at the edge of the surface of the pressure equalizing plate. Four cylindrical limit shells are fixedly connected to the upper surface of the equipment cylinder. The top end of the movable push rod extends into the interior of the cylindrical limit shell and is fixedly connected to a circular plate. A compression spring is fixedly connected between the upper surface of the circular plate and the inner top wall of the cylindrical limit shell. An extension block is fixedly arranged at the end of the shunt tube. A fixed block is fixed on the surface of the movable push rod, and an arc-shaped convex block is arranged on the lower surface of the fixed block.

[0013] By arranging a movable push rod on the surface of the pressure equalizing plate, the air pressure inside the equipment cylinder can be utilized to drive the pressure equalizing plate to move upward, and the movable push rod is driven to drive the circular plate to move upward in the cylindrical limiting shell, while squeezing the compression spring, so that the bottom of the pressure equalizing plate is separated from the surface of the strip-shaped cleaning brush, thereby maintaining the air permeability effect of the equalizing holes. And when the gas stops entering, under the reset action of the compression spring, the movable push rod is driven to reset downward, thereby driving the pressure equalizing plate to reset, and further facilitating the strip-shaped cleaning brush to clean the pressure equalizing plate.

[0014] In a preferred solution, an air inlet hole is formed in the inner bottom wall of the equipment cylinder, and the air inlet hole is used to connect the reduction gearbox with the inside of the equipment cylinder. The inner bottom wall of the equipment cylinder is rotatably connected with an air inlet cover plate, and the position of the air inlet cover plate corresponds to that of the air inlet hole. A limiting baffle is fixedly connected to the inner bottom wall of the equipment cylinder, and the position of the limiting baffle corresponds to that of the air inlet cover plate, and a rubber buffer pad is fixedly connected to the surface of the limiting baffle.

[0015] It should be noted that by arranging the air inlet cover plate and the limiting baffle, when the gas enters the inside of the equipment cylinder 1 from the air inlet hole, the air pressure can be used to push the air inlet cover plate upward, and the opening angle of the air inlet cover plate is limited by the limiting baffle to prevent the air inlet cover plate from failing to reset and close. When the air inlet stops, the air inlet cover plate can automatically cover the air inlet hole under the action of gravity, achieving the purpose of an air inlet one-way valve. In a preferred solution, several turbulence partition plates are distributed up and down in a staggered manner on the inner wall of the reduction gearbox, and the turbulence partition plates form a deceleration channel for the gas inside the reduction gearbox.

[0016] In a preferred solution, a limiting through hole is formed in the central surface of the pressure equalizing plate, and the extension conduit is slidably connected to the inner wall of the limiting through hole. The jet head and the strip-shaped cleaning brush are distributed on the upper and lower sides of the pressure equalizing plate.

[0017] In a preferred solution, an exhaust hole is formed in the upper surface of the equipment cylinder, and an exhaust pipe is fixedly connected to the top of the equipment cylinder, and the position of the exhaust pipe corresponds to that of the exhaust hole.

[0018] As can be seen from the above. A nitrogen making machine energy-saving equalizing hole device provided by the present invention has the following technical effects.

[0019] Firstly: By arranging a pressure equalizing plate inside the equipment cylinder, several equalizing holes on the surface of the pressure equalizing plate can be used to evenly distribute and divert the high-pressure gas entering the equipment cylinder, realizing the transfer and dispersion of gas pressure, reducing the fluctuation of the gas level inside the equipment cylinder, and keeping the equipment cylinder working stably. At the same time, the pressure equalizing plate can also improve the flow field structure inside the equipment cylinder, increasing the smoothness and stability of gas flow.

[0020] Second: By setting up an anti-blocking mechanism, the driving motor can be used to drive the transmission pipe to rotate. Then, the strip-shaped cleaning brush on the surface of the rotating movable frame can be driven by the transmission pipe to clean the bottom of the pressure equalizing plate. At the same time, the air pump is used to convey air into the shunt pipe at the top of the extension conduit, and several air jet nozzles at the bottom of the shunt pipe are used to jet air onto the top of the pressure equalizing plate, so as to achieve the purpose of dredging the flow equalizing holes and improve the cleaning effect on the pressure equalizing plate.

[0021] Third: By setting up the arc-shaped convex block and the extension block, during the rotation of the shunt pipe, the extension block can be driven to push the arc-shaped convex block upward at the same time, and the sliding between the arc-shaped surface of the arc-shaped convex block and the surface of the extension block is utilized to drive the movable push rod to move upward. And under the action of the compression spring, the movable push rod moves downward to reset, so as to make the pressure equalizing plate produce an up-and-down vibration effect, thereby further improving the anti-blocking effect on the pressure equalizing plate.

[0038] It is worth noting that by providing the air inlet cover plate 25 and the limit baffle 26, when the gas enters the inside of the equipment cylinder 1 from the air inlet hole 24, the air inlet cover plate 25 can be pushed upward by the pressure of the gas, and the opening angle of the air inlet cover plate 25 is limited by the limit baffle 26 to prevent the air inlet cover plate 25 from failing to reset and close. When the air intake stops, the air inlet cover plate 25 can automatically shield the air inlet hole 24 under the action of gravity, achieving the purpose of an air intake one-way valve.

The position of the arc convex block 31 corresponds to that of the extension block 29, and the extension block 29 is located below the arc convex block 31, and the arc convex block 31 produces a partial up-and-down effect, so that during the rotation of the extension block 29, the arc surface of the extension block 29 can be in sliding contact with the bottom of the arc convex block 31.

[0042] It should be noted that by setting the arc-shaped bump 31 and the extension block 29, during the rotation of the shunt pipe 705, the extension block 29 can be driven to push the arc-shaped bump 31 on the surface of the movable push rod 20 upward at the same time, and the sliding between the arc-shaped surface of the arc-shaped bump 31 and the surface of the extension block 29 is utilized to drive the movable push rod 20 to move upward, and under the action of the compression spring 23, the movable push rod 20 is driven to move downward for reset, so as to make the pressure equalizing plate 5 generate an up-and-down vibration effect, thereby further improving the anti-blocking effect on the pressure equalizing plate 5.
